Unhinged Creative Product's excellent storage idea for your (1/2 fl.oz) Stickles and ink refill bottles. This unit is 5-3/8 inches in diameter and 3-1/4 inches tall. The units are stack-able and hold up to 18 each of the 0.5 fl. oz. (18ml) bottles such as those used in the popular Stickles products from Ranger. This storage unit holds the bottle inverted to prevent clogging of the tips and the center row is spring loaded to raise the bottles after the lid is removed for easy access. Bottles in photo not included.
